Peer-to-peer (P2P) systems achieve scalability, fault tolerance, and load balancing with a lower-cost infrastructure, from which collaboration systems, such as Wikipedia, could benefit from. A major challenge in P2P collaboration systems, however, is to maintain article quality after each modification at the presence of malicious peers. Therefore, to allow modifications to take effect will be only possible, if a majority of previous editors approve changes by voting. This determines a challenge in P2P systems, due to the absence of a central authority. Thus, this paper proposes the fully decentralized voting mechanism PeerVote, which enables users to vote on modifications in articles in a P2P collaboration system. Simulations and experiments show the scalability and robustness of PeerVote, even at the presence of malicious peers
